ATTORNEYS Patented Dec. 23, 1930 UNITED STATES CHARLES J. MeIiI'rosH, or MILWAUKEE, wrsooivsm, Assienoa T FEDERAL STE-EL PATENT OFFICE SASH COMPANY, OF WA'UKESHA, WISCONSIN, A CORPORATION OF WISCONSIN WINDOW-SASH FASTENER Application filed. October 30, 1926. Serial No. 145,246.

The invention relates to steel sash, and more particularly to the means for holding the ventilator sections of the sash in various opening positions and securing the ventilator section against the adjacent sash frame, when closed, to secure a weatherproof joint.

The object of the invention is to provide a push bar which accomplishes the usual function of holding the sash open at various degrees of inclination, and which also acts as a locking member to lock the ventilator section against the opening in the main frame of the sash so that a forced weathering is secured when the ventilator section is closed.

The invention further consists'in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof. I

In the drawings Fig. 1 is a detail plan view of the device embodying the invention, parts of the sash being shown in section; Fig. 2 is a front elevation view of the device embodying the invention;

Fig. 3 is a detail view of a part of the ventilator section and sash frame with the push bar shown in sash-opening position;

Fig. 4 is a detail section taken on the line 44 of Fig. 2; v

Fig. 5 is an elevation view of a windowsash,

Fig. 6 is an end view of the sash shown in Fig. 5, showing the ventilator section open. In the'drawings the numeral 7 designates the relatively fixed section of the sash frame and 8 the ventilator section, which is shown as hinged at 9 to the stationary section 7 though it may be hinged intermediate its ends, as is well understood in this art. Both the stationary section and the ventilator section of the sash are composed of angles or T-bars and parts of such sections are shown in Figs. 3 and 4, wherein the ventilator section 8 has 7 a lower marginal frame member 10 formed as a T-bar. with vertically-extending pane sections 11 formed as T-bars, and the stationary frame section adjacent the lower edge ofthe ventilator section is formed by a T-bar 12 secured to an angle bar'13.

With thisconstruction when the ventilator section 8 of the sash is in closed position one of the side flanges of the T-bar 10 extends along and abuts against the front of the upper side flange of the T-bar 12, thereby forming a'weather joint and the inwardly extending web 16 of the bar 10 also has weathering Igontact with the upstanding flange of the Theregulator or locking device embodying the invention includes a push bar 14 in the form of an angle bar which has a universal joint connection with the ventilator section by means of a bracket 15'riveted or otherwise suitably secured to the web portion 16 of the frame member 10 and having a vertically disposed pivot pin 17 connected with a pivot block18 which in turn is pivot-ally connected to the push bar 14 by a horizontally disposed pin 19. Thus, by the pivots 17 and 19 disposed at right angles to each other the push bar 14 may be moved either in a plane parallel to the ventilator section of the sash or in a plane at right angles to the plane of the ventilator section so, that when the ventilator section is open the push bar 14 may be turned at right angles thereto and is provided with a series of locking recesses 20, preferably diamondshaped, with an opening at the apex of the recess so as to hooksaid push bar over the top edge of the angle 18 of the fixed portion of the sash. provided so as to secure a variable range of opening positions for the ventilator sections of the sash. Fig. 3 shows the ventilator section of the sash held in one of its open positions by the push bar 14.

. WVhen the ventilator section is in'a closed position the push bar 14 is disposed parallel to the sash and in asubstantia-lly horizontal plane and in order to secure aforced weathering between the ventilator and, fixed sash sections this push bar cooperates with av strike-plate 21 and a locking plate 22.I The strike-plate 21 is a plain surfaced plate which is securediby spot-welding or otherwise to the front face of the angle bar Band in a medial. position relative to the hinge connection for the push bar and the locking plate or clip 22 and is designed to contact with the vertical face 23 of the push bar 14. Thelocking plate 22 has an angle base :portion 24 Several of these notches are secured by bolts 25 and nuts 26, or in any other suitable manner, to the web portion 16 of the frame member 10 and is provided with a bevelled upper edge 27 and apushbar-engaging surface 28. The surface 2? cooperates with the push bar to cam said bar into a locked position when said bar is moved to a horizontal. position, as shown in Figs. 1, 2 and l, and under these conditions the strike-plate 21 is so positioned as to put a spring tension upon the intermediate portion of the bar due to its distortion aroimd plate 2i so as to exert pressure between its spaced points of connection with the ventilator section of the sash, to wit: its pivoted anchorage at one end and its engagement with the lockingplate 22 at the other end, whereby the push bar exerts a pull to force the marginal frame of the ventilator sash section againstthe frame of the fixed section of the sash so that the weathering surfaces of the ventilator section are forced into contact with the fixed flilll'lf} section all points. This springing of the bar ll about the plate 13 is shown in Fig. l wherein the portion of the surface of the bar 14-, in engagement with the plate 21, is shown by the dotted line in front of that portion of this surface, at the point where bar 14L engages the pla e 22.

I desire it to be understood that this invention is not to be limited to any specific form or arrangement of parts except insofar as such limitations are specified in the claims.

Vhat I claim as my invention is:

1. In a device of the character described, the combination with a fixed sash frame and a movable ventilator sash section, of a member carried by said ventilator section and pivoted to swing in a plane parallel to the plane of said section, a. fastening plate, ongageable with one side of said member, soaced from the point of pivotal support of said member and mounted on said ventilator section, and tensioning means mounted on the fixed frame of the sash intermediate the pivotal connection of said member and said fastening; plate and engageable with the other side of said member whereby to produce a tension in said member along the same acting to move the frame of the ventilator section into weathering contact with the frame of the fixed section of the sash.

2. In a device of the character described, the combination with a fixed sash frame and a movable ventilator sash section, of a bar carried by said ventilator section and pivoted to swing in a plane parallel to the plane of said section, a fastening plate on said ventilator section adjacent the free end of said bar and having wedging engagement therement therewith, and means engaging the intermediate portion of said bar and exerting a closing tension along the ventilator section to bring it into weathering contact with said fixed sash frame.

3. in a device of the character described, the con'ibination with a fixed sash frame and a movable ventilator sash section, of a. push bar having connected with said ventilator section for movement in planes at an angle to and parallel to the plane of said ventilator section and movable to engage the fixed sash frame to hold said ventilator section in open position, a fastening member engageable with said bar and mounted upon id ventilator section and spaced from connection, and a strike-plate mounted on the sash frame between said connection and said locking member and exerting a tension upon said bar between its points of connection with said ventilator section when closed whereby to hold said ventilator section in weathering contact with said fixed sash frame.

In testin'iony whereof, I aiiix my signature.
